Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed October 18, 1905- Serial No. 283,336.

To all whom it In/(71,11 concern;

Be it known that I, PHILIP A. SHANKLIN, a citizen of the United States, and a resident of Sandoval, Marion county, Illinois, have invented certain new and useful Improvements in Rolling-Oolter Standards and Fork Attachments, of which the following is a specification containing a full, clear, and eXact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a rolling-colter standard and fork attachment; and the obj ect of my invention is to construct a rollingcolter standard wherein the rolling colter may be quickly and easily adjusted horizontally and vertically by the manipulation of but a single bolt.

To the above purposes my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more clearly set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved attachment in position upon a plow-beam. Fig. 2 is an enlarged vertical section taken on the line 2 2 of Fig. 1. Fig. 3 is an enlarged vertical section taken on the line 3 3 of Fig. 2, and Fig. 41 is a detail section taken on the horizontal line 4 4 of Fig. 3.

Referring by numerals to the accompanying drawings, 1 indicates the standard of my improved attachment, which standard is detachably bolted to the plow-beam in front of the plowshare in any suitable manner. The lower portion of the standard 1 is rounded and bent laterally, as indicated by 2, and the end of this rounded portion is bent backwardly into a horizontal plane beneath the portion 2, as indicated by 3. This portion 3 of the standard occupies a transverse position' directly beneath the plow-beam and is the arm that the clamps of the rolling colter are adjustable upon.

The rolling colter I make use of is of the usual type and comprises a circular disk 4, provided with a hub 5, by means of which it is j ournaled between the lower ends of a fork 6. This fork is provided with a verticallyarranged bearing 7 at its forward upper end, tlnough which bearing is formed an apperture 8, the ends of which are countersunk, as indicated by 9.

1.0 indicates a belt which is provided at its center with a shoulder 11, having a tapered outer surface which is adapted to fit in the countersunk upper end of the aperture 8. The portion 12 of the bolt below this shoulder 11 extends through the aperture 8, and its lower end, which projects beyond the bearing 7, is exteriorly screw-threaded, as indicated by 13. Formed in this lowerportion 12 isavertieallyarranged groove 14. A washer 15, having a conical upper end, is slipped onto the lower end of the portion 12, so that the conical upper end fits in the countersunklower end of the aperture 8. This washer is provided with an interiorly-arranged rib 16, which occupies the groove 14. Located upon the screvw threaded lower end 13, beneath the washer 15, is a nut 17.

A pair of clamping-blocks 18 are provided with oppositely-arranged semicircular. recesses 19, by means of which they are arranged upon the arm 3, and the upper por tion of the bolt 10 passes through suitably-located apertures 20, formed in corresponding ends of these blocks. The upper end of the bolt 10 is screw-threaded and receives a nut 21. Formed through the opposite ends of the blocks 18 are the vertically-alined apertures 22, and passing therethrough is a clamping-bolt 23, on the upper end of which is located a nut 24. A plate 25 is located above the head of the bolt 23 and is provided with a depending finger 26, that extends downwardly between the arms of the fork 6 and prevents said fork from swinging too far to either side. V

When in use, my improved colter travels along in the usual manner in front of the plow, and said colter is free to swing a slight distance to either side, as the bearing 7 journals upon the portion 12 of the bolt 10. When it is desired to adjust the colter laterally or vertically, the operator loosens the nut 24 and by so doing loosens the clamping-blocks 18 upon the arm 3. The clamping-blocks are now free to be moved laterally upon the arm 3 or to be slightly rotated thereon to change the elevation of the disk 4, and after the proper adjustment has been made the blocks are tightened upon the arm 3 by tightening the nut 24 on the end of the bolt 23.

Thus it will be seen how I have constructed a simple inexpensive rolling-colter standard and attachment that may be readily assembled or taken apart which comprises a minimum number of parts and which is adjusted laterally and vertically by the manipulation of a single nut.

The upper end of the standard 1 is made preferably flat, so that it is only necessary to use the old-style two-bar clamp in attaching said standard to the plow-beam, which form of clamp is very simple, inexpensive, and easily operated.

The horizontal portion 3 of the standard may be provided with a series of angular faces, as shown by dotted lines in Fig. 3, or it may be corrugated, so that the clampingblocks 18 may be tightened thereon, so as to avoid all possibility of accidental shifting of said blocks and the parts carried thereby.

I claim- V 1. The combination with a rolling-colter standard, having a horizontally-bent lower end, of a pair of blocks adjustably arranged upon the horizontal lower end, a bolt seated in and projecting downwardly from said blocks, conical bearings arranged on the projecting portion of said bolt, a fork pivotally mounted on said bolt between said bearings,

. and a rolling colter journaled in said fork;

substantially as specified.

2. The combination with a rolling-colter standard, having a horizontally-bent lower end, of a pair of blocks adjustably arranged upon the horizontal lower end, a bolt seated in and projecting downwardly from said blocks, conical bearings arranged on the projecting portion of said bolt one of which bearings is removable, a fork pivotally mounted on said bolt between said bearings, and a rolling colter journaled in said fork; substantially as specified.

3. The combination with a rolling-colter standard, having a horizontally-bent lower end which horizontal end is circular in cross section, of a pair of blocks mounted for adjustment on said horizontal end, lockingbolts passing through the ends of said blocks one of which bolts projects downwardly from the blocks, a fork pivotally mounted on the projecting portion of said bolt, and a rollingcolter journaled in said fork; substantially as specified.

4. The combination with a rolling-colter standard, having a horizontally-bent lower end which is round in cross-section, of a pair of blocks adjustably arranged on said horizontal lower end, bolts passing through the ends of said blocks one of which bolts proj ects downwardly below the lower block, conical bearings on the projecting portion of said bolt, a fork pivotally arranged on said bolt between the conical bearings, and a rolling colter j ournaled in said fork; substantially as specified.

5. The combination with a rolling-colter standard, having a horizontally-bent lowerend which is round in cross-section, of a pair of blocks arranged for adjustment on said horizontal lower end, bolts passing through the ends of the blocks one of which bolts eX- tends downwardly below the lower block, a conical bearing formed integral with said extended bolt, a conical bearing removably mounted on the lower end of said bolt, a fork pivotally mounted on said bolt between the conical bearings, and a rolling colter journaled in said fork; substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
